Interferometric map of the MgNC 8_17/2−7_15/2 emission of the transitions observed within ALMA project 2013.1.00432.S. In the upper left corner of each panel we note the v_LSR of the channel (V_sys = −26.5 km s^-1). The lowest contour corresponds to a value of 3σ, and the rest of contours are equally spaced in jumps of 2σ with respect to the first contour. The rms of the map is σ = 0.9 mJy beam^-1. The beam size is downgraded to that of Fig. A.1 and is drawn in the last panel. The HPBW is 0.′′9 × 0.′′8 with a PA of 33°. The flux density scale is in mJy beam^-1.
